Abstract
Description
- This application claims priority from provisional application serial No. 60/362,205, filed Mar. 6, 2002.
- In conventional residential pool systems, the pool equipment generally includes a heater pump, a filter, and a control system. Generally, the control system is installed on some type of hard surface, such as an adjacent wall, or on some type of supports specifically constructed to provide a rigid mounting point. The rigid mounting points, whether a wall or a newly installed support, must provide enough elevation to hold the electrical contacts above the ground, protecting them from flooding water, and placing access point within easy reach of service.
- Generally, an adjacent electrical service box is provided in which several circuit breakers are provided. These circuit breakers are then electrically connected to relays in the control system housing via conduit. Additional conduits are then installed from the control system housing to the various components of the pool equipment via conduit. This is expensive and time consuming and results in a very complex final installation.
- An integrated heater and control system for a pool or spa is described, and includes a housing structure. A heater assembly includes a burner and a heat exchanger, and is disposed within the housing structure. An electronic control system is mounted within or on the housing structure for controlling the heater assembly and pool or spa functions. In one exemplary embodiment, the control system distributes line voltage power and low voltage control signals to one or more external devices, such as a heater circulation pump and a valve.
- These and other features and advantages of the present invention will become more apparent from the following detailed description of an exemplary embodiment thereof, as illustrated in the accompanying drawings, in which:
- FIG. 1 is a diagrammatic view illustrating an exemplary embodiment of an integrated pool heater and control system.
- FIG. 1A is a fragmentary view of a pressure connector-type connection for the system of FIG. 1.
- FIG. 2 is a side isometric view similar to FIG. 1, but with a side panel of the housing broken away to better illustrate an exemplary heater and control system configuration.
- FIG. 2A illustrates an alternate mounting structure for the control system of the system of FIG. 2.
- FIG. 3 is a schematic diagram of the system.
- FIG. 4 is a simplified top view of elements of the control system mounted in the housing.
- In an exemplary embodiment of a pool heater system in accordance with aspects of this invention, the pool heater, which is typically, but not necessarily, gas fired, is usually of some generous size and proportion, and engineered to sit directly on a hard surface, such as a concrete slab. In addition, the heater is usually engineered to withstand direct rain, as found in an outside installation. In addition, the stable construction of the heater is suitable for the mounting and enclosing of electrical control components.
- Where a pool is equipped with a heater, there has also been the difficulty of finding appropriate places to connect various temperature sensors, water parameter probes and other sensors. In addition, these connections, if not properly made, can result in improper operation of the pool heater and associated equipment. Performing these installations and connections in the factory insures reliable and proper operation. In addition, simple connection points can be provided within or on the housing, eliminating or reducing the need for an electrician to hook up such things as pumps and blowers.
- The total cost of the combined heater/pool control combination can be significantly reduced in exemplary embodiments, as the control housing used in conventional installations is a complex and costly separate enclosure. It should be rain and corrosion proof, be capable of withstanding freezing conditions, direct sunlight, wind, and physical abuse. By incorporating the electrical contents into the heater shell, a much simpler and durable structure is achieved.
- In addition, many control functions which are now duplicated between the control and the heater can be eliminated saving money and installation time.
- The adjacent electrical box can even be provided with a plug properly weather protected and configured for outdoor service, possibly equipped with a ground fault circuit interrupter, eliminating the need for an electrician to perform complex hook up procedures after the electrical box and plug have been installed.
- FIG. 1 is a diagrammatic view illustrating an exemplary embodiment of an integrated pool heater and
control system 50. The system includes aheater housing 1, which is mounted on astable base 12, such as a concrete slab, a floor or the like. The base is typically in an exterior location, although the housing could be positioned inside a shed or other enclosure close to the pool. A main power supply connection 3 is provided adjacent the housing location, e.g. mounted on a wall. The main supply connection 3 preferably includes a ground fault circuit interrupter. The heater main power cord 4 is pluggable into the connection 3 as illustrated. Aconduit 16 leads to a main power supply, e.g. at a main breaker panel. - The
housing 1 supports a water inlet port 5 and awater outlet port 6. Water brought into the housing through the water inlet port 5 is heated by the heater, and the heated water passes out the heater through theoutlet port 6 to the pool or spa. - The
system 50 further includes electrical connectors orterminals 7, mounted at an accessible location on the housing, for connection to external devices such as pumps 8, pool orspa lights 9 and pool or spa valves. These connectors provide an accessible location to make line power or control line connections to the external devices, preferably in this embodiment without the need for a skilled electrician to make complex wiring connections. The connectors orterminals 7 can be plug connectors, terminal block pressure connectors, or other types of electrical connection means. The connectors orterminals 7 are preferably water-tight connectors or terminals.Pressure connectors 7A are shown in FIG. 1A. Alternatively or in addition, ahousing compartment 70 shown in phantom in FIG. 1 can be employed with adoor 70A to provide protection against weather and water intrusion. The electrical wiring leading to the external devices can be brought out at openings in the bottom wall of thehousing 70, in this exemplary embodiment. - In some installations, an optional wireless receiver or
transceiver 14 is connected through the housing to a control system 2 (FIG. 2). This can provide a wireless control link to control the heater and the external devices. The receiver or transceiver can alternatively be mounted within thehousing structure 1, with an external antenna connected to the wireless circuit. Thus, the owner or pool operator can remotely control the pool/spa functions using a wireless remote control transmitter, similar to garage door controllers or vehicle security systems. A coded signal can be employed to control the various functions. - In a preferred embodiment, the
control system 2 is a microprocessor-controlled system, as described in application Ser. No. 09/451,561, entitled CONTROLLER SYSTEM FOR POOL AND/OR SPA, the entire contents of which are incorporated herein by this reference. This control system distributes line voltage and control signals to the external devices 8-10. - A heater control panel11 is positioned on an external surface of the
housing 1 to provide a means for the operator to locally enter commands to control the system. This can optionally include electronic display functions, e.g. using an LCD panel or the like. - An
exhaust gas vent 13 protrudes from a top surface of thehousing 1 to vent hot exhaust gasses away from the system. - FIG. 2 is a side isometric view similar to FIG. 1, but with a side panel of the housing broken away to further illustrate an exemplary heater and control system configuration. As illustrated therein, disposed within the
housing 1 is the heater gas burner 17, coupled throughbarrier wall 35 to thegas line 20 through agas valve 18. Aheat exchanger 19 is disposed above the burner 17, through which the water to be heated is circulated viaports 5 and 6. Sheet metal baffles 21 and 22 direct the heat produced by the burner after passing through the heat exchanger upwardly into thevent 13. - The
control system 12 is disposed in a compartment defined by metal walls includingside walls 41A-C andupright back wall 42; a fourth side wall is defined by the housing itself in this embodiment, although in other embodiments, the compartment can be an integral self-supporting structure such ascompartment 80 shown in FIG. 2A, which can allow fabrication of the control system as a separate module which is then installed on or within thehousing 1 during the fabrication process. In this case, fasteners such as screws, bolts can be used to secure the compartment, or welding can also be employed. A hingedcover 82 allows access to the control unit, preferably with a lock to prevent unauthorized access. - The
control system 2 includes acircuit board assembly 250 to which is mounted a terminal block 240 (FIG. 4). Line voltage supply conductors comprising line 4 are connected to the terminal block by pressure connectors. Theboard assembly 250 includes switches and conductor lines to control line voltage loads and distribute line voltage to the line voltage loads, via conductors connected to terminals on theterminal block 240. The control system board assembly further includes the microprocessor mounted thereon, and switches and signal conductors to control and distribute low voltage signals to control loads and power low voltage loads such as valves. - FIG.3 is a schematic block diagram of the
system 50. For the exemplary implementation of FIG. 3, both aspa 23 and apool 24 are supported by the integrated heater/control system 50. Of course, the system could alternatively be employed for pool only or spa only installations. Water is circulated in thespa 23 by aspa jet pump 8B, which is fluidically coupled towater line 25. Line voltage is supplied to thepump 8B from thecontrol system 2, which also includes switches to turn the pump on and off in accordance with the programmed operation of the system. Theoutlet water line 46 from the heater is passed to a diverter valve 10B to direct the hot water either tospa water line 45 orpool water line 47. Theinlet water line 44 to the heater is connected to an outlet ofheater circulation pump 8A. The valve 10B is controlled by thecontrol system 2. Line voltage is supplied to thepump 8A from thecontrol system 2, which also includes switches to turn the pump on and off in accordance with the programmed operation of the system. Adiverter valve 10A is positioned upstream of thepump 8A to connect eitherspa water line 26 orpool water line 43 to theheater inlet 44. Thevalve 10A is controlled by thecontrol system 2. -
Temperature sensors 20A and 20B are positioned in thewater lines outlet ports 5, 6 of theheater system 50, and provide respective sensor signals to thecontrol system 2. A flow sensor 21 is positioned in thehot water line 46, and is sensed or monitored by thecontrol system 2. The sensor 21 allows the control system to know whether water is flowing through the heat exchanger.

sensor 29 is fluidically coupled to thecold water line 44 in this exemplary embodiment, and its output signal is passed to thecontrol system 2. A pH sensor 28 is positioned inbypass water line 41 between thelines bypass line 41 is smaller than the diameter of the cold and hot water lines, and so water flows at a substantially reduced rate through the bypass line. - In an exemplary embodiment, the
temperature sensors 20A, 20B, the flow sensor 21 and theORP sensor 29 are mounted within or on thehousing structure 1, so that assembly and wiring of these components are performed during the fabrication process for the system. - The
control system 2 receives inputs from the control panel 11 as well as from a wireless control panel 30, which can be mounted remotely from thehousing 1, e.g. at a convenient location in the pool owner's house. Thecontrol system 2 distributes line voltage to the pool andspa lights 9, and includes switches to turn these lights on and off. Thecontrol system 2 also is adapted to pass line voltage and/or control signals to other external devices for performingauxiliary functions 27, such as yard lighting functions, filtration pump, pool cleaner, spa blower, water features, and the like. Thecontrol system 2 includes a microprocessor programmed to carry out a programmed operation, to control the heater burner through thegas valve 18 and thereby control the water temperature according to a desired manner. Thus, thecontrol system 2 not only controls the heater but also the pool and spa devices as well. - FIG. 4 is a diagrammatic illustration of an
exemplary control system 2, which includes acircuit board assembly 250. Line voltage enters thehousing 1 through conductor lines 4 and is connected to aconnector block 240 mounted to thecircuit board 250.

Thecontrol system 2 distributes the line voltage to line voltage external devices, and also includes a transformer 104 (FIG. 4) to generate low voltage dc signals for controlling some or all of the external devices, as well as provide power to the control system circuitry and microprocessor. Thus, in this exemplary embodiment, line voltage is provided tosystem 50 through a single line voltage connection, which can be a hard-wired connection, or a plug-in connection. The line voltage wiring to the line voltage loads is illustrated generally as wiring 120 in FIG. 4. Low voltage wiring to low voltage loads is indicated generally aswiring 130. - Some of the advantages of exemplary embodiments of this invention include:
- i. a single assembly can be provided which can be electrically connected with one electrical service, thereby reducing installation costs;
